How does Jem change in Ch. 14?

In Chapter Fourteen, Jem's behavior seems to betray Dill and demonstrates his progress into the adult sphere. In addition, he suggests that Scout be less defiant toward their aunt, putting himself onto the adult side of the argument, to Scout's annoyance. The interaction between the two suggests that children (like Scout) are more immune to the attitudes and mindsets of the society around them, but as they grow older (like Jem), they unwittingly find themselves replicating and reinforcing society's traditional views.
